Is that possible to add some actions to the "grabbed object"

Is that possible to add some actions to the "grabbed object"

the object is grabbed on the mouse or other equipment and I want to add some action to the grabbed object such as spinTo, sizeTo, but different signal input trigger different actions

it is not the "grabber.GRAB_EVENT", this event can only trigger one movement after it is grabbed.

I want to trigger different movement.

Thanks

You could set a flag when the object is grabbed. When the input signal is sent, check to see if the object is grabbed before applying the action:

Code:

import viz

import vizconnect

import vizshape

import vizact



vizconnect.go('vizconnect_config.py')



dojo = viz.addChild('dojo.osgb')



torus = vizshape.addTorus(radius=0.1,tubeRadius=0.015,axis=vizshape.AXIS_X, pos=[0,1.7,1])

torus.texture(viz.addTexture('images/tile_wood.jpg'))

torus.addAction(vizact.spin(0,1,0,15))

torus.grabbed = False



grabber = vizconnect.getRawTool('grabber')

grabber.setItems([torus])



def onGrab(e):

        if e.grabbed == torus:

                torus.grabbed = True

        

def onRelease(e):

        if e.released == torus:

                torus.grabbed = False



from tools import grabber

viz.callback(grabber.GRAB_EVENT, onGrab)

viz.callback(grabber.RELEASE_EVENT, onRelease)



scaleAction = vizact.sequence([vizact.sizeTo(size=[1.3,1.3,1.3],time=1),vizact.sizeTo(size=[1,1,1],time=1)], viz.FOREVER)



def applyScale():

        if torus.grabbed:

                torus.runAction(scaleAction,pool=1)

                

def removeScale():

        if torus.grabbed:

                torus.clearActions(pool=1)



vizact.onkeydown('1',applyScale)

vizact.onkeydown('2',removeScale)

                torus.clearActions(pool=1)



vizact.onkeydown('1',applyScale)

vizact.onkeydown('2',removeScale)

is that possible to do these in VizChild object like osgb file

vizact.onkeydown('1',applyScale)

vizact.onkeydown('2',removeScale)

and also why it shows "VizPrimitive" object has no attribute "grabbed"

Yes, you can also define an attribute such as

Code:

torus.grabbed = False

for a node3D object created from an osgb file.

I'm not getting the same error. What version of Vizard are you running?

I fixed the problem

I forgot to add the code "viz.callback(grab.GRAB_EVENT,onGrab)"
